There are two types of limits:

  • Technical limits (hard-coded limits) are maintained by technical means. They cannot be exceeded.
  • Recommended limits (soft limits) are not enforced by technical means. They can be exceeded.
  • The limits are defined to ensure the full and correct functioning of the system. Consult Headquarters before exceeding the recommended limits. HQ can modify the recommended limits on the basis of new findings at any time. Changes are notified in Facts bulletins.

Certain limits cannot be verified (for reasons of cost or quantity). These limits are shown in this document as follows:
